Lemongrass is a plant whose leaves and the oil are used to make clinical medicines.
Lemongrass is used for treating digestive tract spasms, stomachache, high blood pressure, convulsions, pain, vomiting, cough, achy joints (rheumatism), fever, the common cold, and exhaustion.
It is also used to kill germs and as a mild astringent.
Some people apply lemongrass and its essential oil directly to the skin for headache, stomachache, abdominal pain, and muscle pain.
By inhalation, the essential oil of lemongrass is used as aromatherapy for muscle pain.
In food and beverages, lemongrass is used as a flavoring. For example, lemongrass leaves are commonly used as “lemon” flavoring in herbal teas.
In manufacturing, lemongrass is used as a fragrance in soaps and cosmetics. Lemongrass is also used in making vitamin A and natural citral.
How does it work?
Lemongrass might help prevent the growth of some bacteria and yeast. Lemongrass also contains substances that are thought to relieve pain, reduce fever, stimulate the uterus and menstrual flow, and have antioxidant properties.
Uses & Effectiveness
High cholesterol. Early research suggests that taking lemongrass oil by mouth for 90 days does not reduce cholesterol levels in people with high cholesterol.
Yeast infection in the mouth (thrush). Early research suggests that drinking a lemongrass infusion for 10 days decreases thrush symptoms in people with HIV/AIDS better than applying a solution of gentian violet to the affected area.
Stomach and intestinal spasms.
High blood pressure.
Achy joints (rheumatism).
Use as an antiseptic and astringent.
More evidence is needed to rate the effectiveness of lemongrass for these uses.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
Lemongrass is LIKELY SAFE for most people when used in food amounts. It is POSSIBLY SAFE when taken by mouth or applied to the skin short-term for medicinal purposes.
However, there have been some toxic side effects, such as lung problems after inhaling lemongrass and a fatal poisoning after a child swallowed a lemongrass oil-based insect repellent.
